Product Profile
Product Profile
EKR3L smart RCBO offers not only overload, short-circuit, and leakage protection like traditional circuit breakers, but also the ability to be remotely controlled and monitored through the Tuya APP. It also provides an automatic reclosing function to improve the reliability of the circuit power supply.
EKR3L Smart RCBO combines traditional RCBO protection features with modern smart home technology, providing users with enhanced safety, convenience, and control over their electrical systems. It is particularly useful for remote management of electrical circuits and can be integrated into broader smart homes or building automation systems.
This product page is for the WiFi (Tuya) communication variant of EKR3L (type code communication method: 0; optional recloser code: 03).
